Abstract

The aim of the inventions is to measure the intensity of electromagnetic radiation (L) hitting an optoelectronic measuring device (1). This aim is achieved in that the electromagnetic radiation (L) is detected by means of a first detector (10), a first detector signal thus being provided. Furthermore, the electromagnetic radiation (L) is detected by means of a second detector (20), a second detector signal thus being provided, a spectral filter (24) being arranged in a beam path (S) upstream of the second detector (20) in order to filter the electromagnetic radiation (L) before detection by the second detector (20). By means of a signal difference determiner (30), a difference signal is produced by subtracting the second detector signal from the first detector signal.
